Without the engine code numbers, any answer would be wild speculation.
Some cars require a OBD reader. Others will flash the error code on the dash when a jumper wire to attached to a plug underneath the dash. Montgomery County library often has books for each car model that would describe how to get the "DTC" code.
Without that code, I could think of at least 12 different items that would explain that behavior. The actual list is far longer. First get the DTC number.
